Tsai Eng-meng (Chinese: 蔡衍明; pinyin: Cài Yǎnmíng; born 1957) is a Taiwanese businessman.

"[7] In 2024, Tsai brought a civil lawsuit against Wikimedia Taiwan chapter after he was reverted by editors on Chinese Wikipedia from editing content that reflected his pro-China stance on the biographical article of himself.

Tsai believed that the content injured his reputation and personality rights, and filed the lawsuit to compel Wikimedia Taiwan to allow him to edit the article.

The lawsuit was dismissed after the court found that Wikimedia Taiwan had no control over Chinese Wikipedia and also did not prevent Tsai from editing.

[5] His older son, Kevin Tsai runs the family's media empire of TV stations and newspapers.
